Solvable Models for radiating Black Holes and Area-preserving Diffeomorphisms
J. Cruz, J. Navarro-Salas
Solvable theories of 2D dilaton gravity can be obtained from a Liouville theory by suitable field redefinitions. In this paper we propose a new framework to generate 2D dilaton gra…
Higher-Order Differential Operators on a Lie Group and Quantization
V. Aldaya, J. Guerrero, G. Marmo
This talk is devoted mainly to the concept of higher-order polarization on a group, which is introduced in the framework of a Group Approach to Quantization, as a powerful tool to…
The Role of Temperature in a Dimensional Approach to QCD_3
A. Ferrando, A. Jaramillo
We analyze the role played by temperature in QCD_3 by means of a dimensional interpolating approach. Pure gauge QCD_3 is defined on a strip of finite width L, which acts as an inte…
Yang-Baxter equation and reflection equations in integrable models
P. P. Kulish
The definitions of the main notions related to the quantum inverse scattering methods are given. The Yang-Baxter equation and reflection equations are derived as consistency condit…
Algebraic Quantization, Good Operators and Fractional Quantum Numbers
V. Aldaya, M. Calixto, J. Guerrero
The problems arising when quantizing systems with periodic boundary conditions are analysed, in an algebraic (group-) quantization scheme, and the ``failure" of the Ehrenfest theor…
Group Theoretical Foundations of Fractional Supersymmetry
Jose A. de Azcarraga, Alan J. Macfarlane
Fractional supersymmetry denotes a generalisation of supersymmetry which may be constructed using a single real generalised Grassmann variable, , for arbitrar…
